Learn Russian: Зимой я хожу в перчатках.

In Russian, a common way to describe habitually wearing an item of clothing is to use the verb ходить (to walk/go) plus the preposition в and the Prepositional case. You are literally saying, "In winter, I walk around in gloves."

Is перчатки a plural-only noun like очки or деньги?

Not strictly. Unlike очки (glasses), which has no singular, you can say перчатка for a single glove. However, since they are worn in pairs, they behave much like plural-only nouns in daily use. Here, перчатках uses the standard Prepositional plural ending -ах.

Could I use the verb носить (to wear) instead?

Yes! You can say Зимой я ношу перчатки. Both options are perfectly natural. Just keep in mind that носить takes the Accusative case (no preposition), while ходить requires в plus the Prepositional case.

Why does "in winter" translate to just зимой without a preposition?

To say that something happens during a specific season, Russian uses the Instrumental case of the season's name without any preposition. The noun зима (winter) changes its ending to become зимой (in winter).
